Regarding the July 5 article “North Korea missile test: How big a technological breakthrough?” (CSMonitor.com): Rather than impose tougher sanctions on North Korea, perhaps the United States should undergo a complete nuclear disarmament. North Korea’s efforts to become a nuclear state are their way of “keeping up with the Joneses.” They want to show the world that they are just as good as everyone else. As long as the US remains a nuclear state, it should not have jurisdiction to cherry-pick those nations allowed to have nuclear weapons.
